Actuation refers to the process of causing a device or system to operate or move. It typically involves converting energy from one form to another, such as electrical energy into mechanical motion. Actuators, which are components that facilitate actuation, can be found in various applications, including robotics, automotive systems, and industrial machinery. In engineering, actuation is crucial for controlling systems and enabling automation. Common types of actuators include electric motors, pneumatic cylinders, and hydraulic systems. Each type has its advantages and is chosen based on the specific requirements of the application, such as speed, force, and precision.
